CORONADO, Calif. -- Conclusion to a nearly month-long death mystery at the Spreckels Mansion on Coronado could come by the end of next week. 

The San Diego Sheriff’s Department said Tuesday it expects to release information on the death of 32-year-old Rebecca Zahau as soon as it gets toxicology results, which could be by next Friday.

Zahau was found hanging from a balcony inside the mansion on July 13th with her hands and feet tied  behind her back.  Zahau was the girlfriend of Arizona multi-millionare Jonah Shacknai

Two days before she died, Shacknai’s 6-year-old son Max was fatally injured after falling near a flight of stairs.  His death is being investigated by Coronado Police as an accident.  Rebecca Zahau and her 13-year-old sister were the only other two people inside the home when the fall happened.  Police said Shacknai was returning from the gym at the time.Both deaths have grabbed national attention as investigators still try to determine what happened.

Monday, Mr. Shacknai spoke publicly for the first time, addressing shareholders during a quarterly earnings report.

Shacknai did not address exactly what happened, only saying "we've obviously had an extremely difficult time.  We have undertaken some tragedies, some losses that couldn't imagine experiencing in a lifetime."

Also Tuesday, the Sheriff’s Department said it had concluded all interviews.  Investigators also pieced together what happened in the mansion the night before Zahau was found dead, contradicting reports from neighbors there was a party inside the home.

The Sheriff’s Department also denied reports from an online tabloid that suicide had been ruled out in the death of Zahau.  Lt. Larry Nesbitt from the homicide division called the story, “wrong”.
